MEDICAMENT VAPORIZER AND BURNER.

Specification of Letters Patent.

. Appncation mea January 11, 1912. serial No. 670,613.

To all whom it may concern Be it known that I, GEORGE W. BENNETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Medicament Vapor-v izers and Burners, of which the following is a specification.

My invention relates to burners or heaters and while I have in the present instance shown my invention as embodied in a burner for a medicament vaporizer and used in connection with certain parts going to make up a complete apparatus of thischaracter, yet as hereinafter made' apparent, my burner may be used for different purposes and with a different character of fuel than asv usually.-

employed in such vaporizers.

VThe object of my invention is to provide a simple compact portable burner or heater n arranged to use any suitable fuel such as alcohol, kerosene2 paraiiin, etc. WhenV lthe burner is used 1n connection with a vaporizer the liquid-holding receptacle which con-v tains the medicament and its holder is utilized as an inclosing box or casing, the cover of such box being also utilized as a support or stand for the burner, etc. l

The various features of advantage and utility-of my invention will b eyapparent from the description'hereinafter given. Y

In the drawing Figure lis a central section of my burner'forminga part of a vaporizer, all of the parts being here shown i n their assembled -or packed form; Fig. 21s a similar section illustrating4 dierent parts in positionfor use asa vaporizer; Fig. '3v

a perspective of the cupl or fuel receptacle of the burner illustrated in Figs. 1 and 2.; Fig. 4 a sectional elevation similar to that of Fig. 1 but illustrating a modied construction; Fig. 5 a perspective of the cup or fuel receptacle of Fig. 4 and Fig. 6 a detailed view of another modified construction of burner.

Referring to vention.v as illustrated in Figs. 1, and 3 and describing lit as usedv in connection with a vaporizer, the burner consists essentially of a fuel receptacle and a wick'extending upwardly along the inner sides of such receptacle and projecting laterally therefrom,

the embodiment of 4my insuch receptacle lbeing so constructed as to support'another receptacle of larger size or diameter containing the liquid in which the medicament is placed. In Figs. 1 and 2 this fuel receptaele'is shown as comprising two portions and in Figs. 4 and 5 as comprising a single portion.

Referring to Figs. 1, 2 and 3 the fuel receptacle consists of a cup 1 open at its top and closed at its bottom and an inner shell 2 which is of such a 'diameter thatwhen it is introduced within the cut it forms therewith an annular space adapted to receive the wick. By'preference a plurality of wicks 3 are'employed the same rising vertically along the inner walls ofthe cup and within said annular space and `being preferably in contact with a wick' 4 resting upon the bottom ofthe cup and common to all of the wicks 3. lThis Aannular space which contains the wicks has communication in any suitable manner withthe'interior of the shell 2, as for instance bymeans of the openings 2@L at the bottom` thereof. The interior of this shell forms a fuel chamber in which may be introduced any suitable fuel indicated at 5, such as alcohol, kerosene, paraifm, etc., the latter being the fuel preferred, when the device is to be used as a vaporizer. The cup 1 is provided at its' upper portion with `a series of wick openings la formed by notching the upper'edge oflsuch cup, as clearly illus- The Vinner shell is'provided with a series ofk rightangled marginal flanges 2b, 2c and 2d, the flange 2b resting.- upon the top edge of the cup' 1 andprojecting togetherwith the other ianges beyond the lines of the cup. The top or outermost iange 2@ forms a support for the box or receptacle 6 which is of greater size or diameter than the burner.V

This latter receptaclel is adapted to contain the medicament'holder'7, the medicament,

such as formaldehyde, being contained in a suitable,y holder indicated at 8. In practice this receptacle 6 together with the lid 9 forms a box or inclosing easing for the remainder of the parts as indicated in Fig. 1

and the same are utilized ras'parts of theY f vaporizer as shown in Fig. 2, the receptacle 6 containing the Water or liquid in Which the medicamentholder is immersed and the lid 9 forming a support or stand for the burner.

' As shown the cup or Vouter shell ly andthe inner shell 2 are cylindrical and are concentrically arranged with theresult that anannular space is formed between their Walls. The'wvick fits vigthinthis' annular space and in practice the Wick is inserted Within the cup or outer shell before the inner shell is introduced, so that the Wick has an equal pressure Vappliedto it all around in Vcase of a single wick or the separate Wicks have a pressure applied thereto which is uniform, with the 'resultthatthe'rate of feed of fuel is established 'and made uniform `all the Way aroun'd the burner, that is on all sides thereof. Y

When the parts arefassembled andpacked ready for the'r'narketI they have the relative position `indicated in Fig. 1 wherein it is seenv that the burner isv placed Within the box 6 iviththe'medicament holder in inverted position supported upon the burner, and with la sealing ,pad l0 of suita-ble'material s'uchas parafline'd paper interposed between such holder and the' burner, as clearly shown in Fig. l. ln order tokeepthe'contained parts inproper position Within the'box l vprefer to form upon thei bottom of the Ybox a Y projection Vwhich is in thepresent instance a circular bead Ga *ofY fa diameter slightly greater than that of the cup' portion l of the burnerfivhereby theparts 'vvithin the box are maintained in a central position. f Moreover, the cover 9 of the boxis adapted, vWhen fitting upon the body portion of said box7 to press against the central portion of the convex bottom of the holdern?7 at vhich ltimeV Y Y. such holder is in inverted posi-tion. VThe bottom of the holder is by' preference made convex `as gust statedinY order-'to insure a central contact or point of. pressure Ybetween,

the lid and such holderwiththe resulty that.V

theV parts are held-firmly Within the box.

The yholderV 7-is provided -iv-i'th a-Vhorizo'ntal Y flange 7l1 and also a vertical marinal flange b Y b b 7b whichl vflanges cooperate with the flange 2d -of the-burner yand 'Withthe Ysealing Vpad in Y order to seal the contents ofthe holder, such Vnad beingv held against displacement by means of the marginal flange' 7b.

' Assuming that( the burner-is used in connection v'ith 'a vaporiz'enthe `partsY are un'-VV paeked from'the position shown :in Fig. l,

andplaced in the relative position shovvn in Fig. 2,V Water being introduced into` the receptacle'o. V'lhe'vvicks arenoW lightedV and somefof the wheat is conducted downwardly by the cup-and inner shell to the fuehwherebythe latter, if vofthe-solid or parafi'in charmaar, is 'caused 'to mut at 'points adjacent the Wicks whereby thevvick's are kept sup- Y;

plied With the fuel. The use of the common Wick a in the bottom of the cup'serves to feed all of the fuel therewithin to the several wicks.

In Fig. 4I have shown a modified form of ".1

construction inV which the fuel receptacle is shown as made-in a single piece7 Vthe same being a receptacle or cup llv having a marginal flange l1?l and a series of slots 1lb in the upper portion thereof through Which the Vplurality of Wicks 3 project at their upper vertical flange -lila Vwhich prevents the disf placement of the sealing pad.

By preference and as sho\vn,'the box or container 6 is Iprovided at its centraljportion With a depending .projection which is here inthe form of a circular bead vvhi'ch is engaged by and coperates with the burner and therebyholds the box in proper central position.y Moreover, by preference this box is providedat its lowery corner with V'a depending marginalextension or flange Gelthe pur- 'r pose of Which is to prevent any flame from passing' straight up .alongV the side of the box and thereby lessening the danger of the ignitiirlig of any fumes from the-medicament use 'lt will be understood fromV the foregoing description that the burner may be .employed Vfor any heating-purpose besides the heating of` Water for vaporizingrpurposes and also that any' suitable *fuelv may-be used. The construction shown enables the parts to be Vpackedvthin very small compass and providesv apackage'ofa regular or smooth exterior surface.V Furthermore, the construction and arrangementare such thatthere is no danger of they fuel catching ire'ev'en' though the YWater i-nwfthe receptacleforbox 6 may have been Y entirely evaporated. Sufficient heat is conducted by the Ymetalof the burner tiomelt-the soli-d fuel if-Vu'sedbut4 the interior 3 of the'rfuel chamber is closedagainst any possible entrance yof theV :dame itself thereto so that there is no danger of the bodyof the fuel catching fire. This latterv feature 'is of considerable Vimportance especiallyY When the deviceis used as a vapo'rizer7V in which case theburner is lighted and leftto'burn itself out in rooms orl spaces Whichare closeda d unattended.

The sealing padrisr preferably inade'of thick paper, such as blotting paper or other substance of an absorbent nature, such as asbestos, which when saturated with paraffin, with the resultant tendency to adhere to the adjacent flanges, forms an hermetical seal, preventing deterioration of the medicament while stored for sale or future use.
